Don't know if you all saw it, but apparently Steve Danuser has indeed left Blizzard, all the way back to November last year. Just saw a spanish wow website report on it.
I guess that makes sense with how Metzen has been very clearly in charge of the narrative direction of the game. And personaly, even though I tend to not be so negative as most, I do think there were glaring narrative missteps in the past few expansions under his watch. So I wish him the best of luck. And hope for a return to form for wow under Metzen's leadership.
